Air Fryer vs Oven: Which Saves More Money？
With the British weather being its usual unpredictable self, the only thing we can rely on lately is the constant urge to check the smart meter. As energy prices bob up and down, the debate of oven vs air fryer has shifted from fancy recipes to the appliances themselves. Is it actually cheaper to whizz up some chips in an air fryer, or are you better off sticking with the trusty built-in oven?
In this guide, we’re going to look at what it really costs to keep your kitchen running. We’ll pinpoint where you might be throwing money away and, more importantly, how a bit of clever tech can help you get that Sunday roast on the table without the usual side order of "bill anxiety."
Which Appliance Costs Less to Run?
Before we dive into the tech, let’s look at the raw data. It’s not just about the wattage; it’s about how that energy is used from the moment you flick the switch.
1. Compare Preheating vs. Instant Start Efficiency
Think of an air fryer as a compact, turbo-charged version of your oven. Because it’s so much smaller, it hits cooking temperature the moment you flick the switch. Compare that to a standard UK electric oven, which usually spends 10 to 15 minutes just "getting ready." That’s a quarter of an hour where you're paying for electricity to heat up empty air before a single potato has even had a chance to crisp.
2. Assess Daily Energy Draw per Meal
For a quick mid-week meal—say, a couple of chicken breasts and some veg—the air fryer is the clear winner. It uses roughly 1.4kWh to 1.7kWh per hour. For a typical 20-minute air fryer meal—like a batch of chips or a roast chicken portion—this translates to roughly 35p–50p per meal, compared with £1.20–£1.60 if you used a conventional electric oven for the same dish. That’s nearly 3x cheaper per meal, making the air fryer ideal for quick weeknight dinners.
3. Calculate Monthly Costs for Family Cooking
When you scale this up to a month of family dinners, the savings add up. If you swap three oven sessions a week for air frying, you could be looking at a saving of £5 to £10 a month depending on your tariff. It sounds modest, but over a year, that’s a nice dinner out (or a very posh takeaway).
4. Analyze Annual Electricity Price Differences
The real sting comes from the long-term trend of UK energy prices. Relying solely on the grid means you’re at the mercy of the market, which is why keeping an eye on the energy price cap is essential for budgeting your monthly kitchen spend.
Here’s a clear breakdown of how much you can save with an air fryer compared with a standard oven, both in cost and energy efficiency.
| Feature | Air Fryer (Typical) | Electric Oven (Typical) | Savings % |
|---|---|---|---|
| Average Power Rating | 1,500W | 2,500–3,000W | ~40–50% less power draw |
| Preheat Time | 2–5 Minutes | 15 Minutes | ~70–85% faster |
| Cooking Speed | Fast (High Airflow) | Standard | ~25% quicker meals |
| Heat Loss | Minimal | Significant | ~60–70% less wasted energy |
| Annual Running Cost (Est.) | £60 – £85 per year (≈ 35–50p per 20-minute meal, based on 24–30p/kWh, Ofgem 2026 tariff) | £160–£210 | ~60% savings |
| Total Carbon Footprint | Lower (Less run time) | Higher (More energy/heating volume) | ~55–60% lower |
Pro Tip: The "Batch Cooking" Rule The air fryer is a sprinter, but the oven is a marathon runner. If you are cooking for 1–2 people, the air fryer is unbeatable. But when preparing a full family Christmas dinner or multi-layered bakes, the large oven cavity allows you to cook everything at once, making its energy-to-food ratio more efficient than running a small appliance multiple times.
Why Do Your Energy Bills Stay High?
You’ve bought the air fryer, yet the bill is still eye-watering. Why? It’s often down to the "invisible" drains in our British kitchens.
1. Vampire Power
That little clock on your oven and the "ready" light on your air fryer might seem harmless, but "vampire power" (standby electricity that appliances draw even when off) across all kitchen gadgets can account for up to 10% of a household bill.
2. Instantaneous Draw
This instantaneous draw can easily blow your budget if it happens during peak grid hours. The trick is to play it smart: by timing these power-hungry tasks for when your solar panels are soaking up the sun, you can ensure that big energy spike is covered by your own green power, rather than the expensive National Grid.
3. Energy Waste in Large Oven Cavities
Heating a massive, 70-litre oven just to crisp up a single tray of Mediterranean veg is like turning on the central heating for the whole house just to stay warm in one armchair. It’s a huge waste of energy. Most of that heat is simply warming up empty air, making it one of the most expensive ways to cook a side dish.
4. Kitchen Heat Leakage and AC Strain
In the warmer months, a conventional oven is essentially a giant radiator you didn't ask for. It pumps so much heat into the room that your kitchen becomes a sauna, forcing your fans or AC to work double-time just to make the room liveable. By switching to an air fryer or investing in home battery storage to offset these peak-time cooling costs, you stop paying twice—once to heat the food, and again to cool the room back down.
How Can You Automate Your Savings Effortlessly?
If you’re tired of playing "energy detective," it’s time to let technology do the heavy lifting. You shouldn't have to eat dinner at midnight just to save a few pence.
1. Leverage Battery Storage to Skip Peak Prices
Dinner time is usually the most expensive "peak" period and the most energy-intensive time for a home. Instead of delaying dinner to save money, you can use the EcoFlow PowerOcean (Single-Phase) home battery system to achieve "energy freedom." It automatically stores electricity when prices are low (or when your solar panels are soaking up the British sunshine) and discharges it precisely when you turn on that power-hungry oven. By using this "peak shaving" strategy, you’re essentially paying for today’s roast with last night’s cheap electricity.
2. Centralize Kitchen Energy Tracking via Smart Dashboards
Once you have the hardware, you need the "brain" to manage it. The EcoFlow PowerInsight 2 is exactly that. It transforms complex energy data into an intuitive dashboard, letting you see the real-time power draw of your appliances at a glance. When you can actually see the spike in usage as the oven kicks in, you can better coordinate your cooking—and with the PowerOcean system, you can ensure you're always using the most cost-effective power source.
3. Sync Appliance Schedules with Solar Generation
If you’ve got solar, it’s all about “use it or lose it.” Instead of letting that green energy go to waste, you can sync your heaviest cooking—like that big Sunday meal prep—to the exact moment your panels are soaking up the midday sun. By utilizing a home energy management system, you can automate these decisions based on weather forecasts and real-time generation. It’s a brilliant feeling knowing your roast is essentially being powered for free by the weather.
4. Integrate Smart Thermostats to Offset Oven Heat
Modern smart home setups can talk to each other. When your oven is pumping out heat, a smart thermostat can dial back the kitchen radiator, ensuring you aren't paying twice to heat the same room.

What Are the First Steps to Reduce Your Kitchen Energy Bill?
Ready to take action? Here’s how to start trimming the fat off your energy spend:
1. Audit Your Current Kitchen Power Usage
Spend a week noticing which appliances are on the most. Is the kettle constantly boiling? Is the oven on for two hours for a 40-minute dish? These observations are the first step in learning how to make your home more energy-efficient from the kitchen outwards.
2. Identify High-Consumption Cooking Habits:
Batch cooking is your friend. If you must use the oven, fill every rack.
3. Compare Energy Star Ratings for New Appliances:
If your oven is an antique, it’s likely costing you a fortune. Look for A+++ rated modern replacements.
4. Upgrading Inefficient Appliances:
Sometimes, the best way to save is to spend. Swapping a legacy electric hob for induction, can pay for itself in long-term savings.
